docker：安装redis

文章来源:https://www.cnblogs.com/hello-tl/p/9239474.html

1.添加镜像

# docker pull redis:4.0

2.在/data下新建文件夹redis，进入redis文件夹新建文件夹conf4.0

# mkdir /data
# mkdir /data/redis/conf4.0

3.创建并写入 redis.conf

# vim /data/redis/conf4.0/redis.conf
  内容
    bind 0.0.0.0
    # 端口
    port 6379
    # 持久化
    appendonly yes

    requirepass password

4.执行命令启动

# docker run -d -ti -p 6379:6379 --net docker_default \
-v /data/redis/conf4.0/redis.conf:/usr/local/etc/redis/redis.conf \
-v /data/redis/data:/data --restart always --name redis4.0 \
--sysctl net.core.somaxconn=1024 \
redis redis-server /usr/local/etc/redis/redis.conf

5.执行命令解说

1、-p是指启动的端口
2、第二行指定了配置的位置，命令指的是刚刚复制的配置，配置中有端口、密码等重要参数
3、第三行开始的是指定数据存储位置，--restart always是自动重启，--name redis4.0设置容器的名字为redis4.0
4、第四行设置tcp内核参数，默认512
5、启动镜像名和服务、配置（固定不能变）

6.简单操作

[root@localhost conf4.0]# docker run -it redis:4.0 redis-cli -h 172.17.0.1 -p 6379 -a password
